07 Tahoe LTZ:

While cutting the spare tire down and replacing the stupid spare tire hoist I found this module up there and it's sitting lose, looks like the mounts rotted away. Any idea what this module is for? Anyone else have to re attach this unit? any ideas would be welcome.

This is above the spare tire:

 

if your underhood fuse box has a empty space where the fuel pump relay and fuse go; its probably the fuel pump control module.

 

Thats the AutoRide/Electronic Ride control Module. DO NOT TOUCH IT! Its in such a place that the small bolts that hold it into its bracket rust very easy. I poked mine and literally all 4 bolts popped right then.... (on the 07)


Just follow the harness. Not hard. Its the same harness for the compressor (in pic), the two rear shocks, and two rear ride height sensors...

 

I think he is correct. Secure it, don't let it flop around.

 

Yep, that's the problem I touched it as it looked to just be laying there and it moved, so I was trying to figure out how it's supposed to be attached to try and fix it. But before I could look up how to fix it I needed to know what it was. So any ideas on how to attach it?
